Manufactured from hot-rolled alloy steel bars with automated high-speed hot forging for end upsets. Full-length normalization relieves residual stresses, followed by air-quenching and tempering to refine grain structure. All bars undergo straightening and Eddy Current inspection for surface defects, with final surface shot-cleaning to remove heat treat scale.
Sucker rods connect surface pump jacks to downhole reciprocating piston pumps in oil wells. We also provide comprehensive rod accessories including polished rods, sinker bars, rod couplings, and pony rods. API type T or spray metal couplings available in pin sizes 5/8" through 1 1/8" in full size or slim-hole diameters.
